Fracturing blender tank, fracturing blender truck and fracturing truck unit

Abstract

The invention discloses a fracturing blender tank, a fracturing blender truck and a fracturing truck unit in order to improve the uniformity of a fracturing fluid and the fracturing quality and reducing the energy consumption of equipment. The fracturing blender tank comprises a tank body, a leaking plate, an introducing pipe and a lower plate, wherein the leaking plate, the introducing pipe and the lower plate are sequentially arranged in the tank body from top to bottom and are coaxially arranged; an opening is formed in the top of the tank body, and a fracturing fluid outlet is formed in the bottom of the tank body; the introducing pipe comprises a nozzle part and a flaring part, wherein the nozzle part upwards extends after penetrating through an opening in the bottom of the leaking plate, and a gap is retained between the flaring part and the opening in the bottom of the leaking plate; and a gap is formed between the lower plate and the flaring part along the axial direction, the upper surface of the lower plate is provided with a bulge corresponding to the center of the flaring part, and an opening communicated with the space inside the tank body is formed between the edge of the lower plate and the tank body.

Description

technical field [0001] The invention relates to the technical field of oil field fracturing equipment, in particular to a sand mixing tank, a sand mixing vehicle and a fracturing train set. Background technique [0002] In the recovery process of oilfield crude oil, it is necessary to increase the recovery rate through the fracturing process. As the core equipment of the fracturing crew, the sand mixer plays a vital role in the oilfield fracturing process. In the sand mixer truck, the sand mixer tank is the core component that mixes the sand with the base fluid. Such as figure 1 As shown, when the sand mixing vehicle is in operation, the base liquid is injected from the base liquid injection port 50 of the sand mixing tank 100, and the sand particles are added from the top of the sand mixing tank 100 by the sand adding mechanism, and the sand particles and the base liquid are in the sand mixing tank 100. After being stirred by the stirring impeller 70 in the tank, a fract...

AI Technical Summary

Problems solved by technology

[0003] The defect of the above-mentioned prior art is that the sand particles entering the sand mixing tank are easy to aggregate, and due to the limited stirring effect of the stirring impeller, it is difficult to mix the sand particles and the base fluid evenly, so that the fracturing fluid delivered to the main press vehicle The uniformity is poor, seriously affecting the quality of fracturing

In addition, the stirring impeller is driven by a hydraulic motor when it is working, and the stirring energy consumption is relatively high
